The makers of the Cherie Currie and Joan Jett biopic, The Runaways, seem very keen to show off that Dakota Fanning and Kristen Stewart played their own instruments and did their own singing in the film. As a result they’ve released a music video of the duo singing what is perhaps the rock band, The Runaways, most famous song, Cherry Bomb. It’s not as bad as you might expect, and suggests this may actually be a pretty good, gritty flick, which charts the jailbait rockers’ brief career, which saw them rise to fame, but then implode due to drugs, sex and in-fighting.
